Abstract

Die Erfindung betrifft eine Ventileinrichtung (100) zum gesteuerten Einleiten eines Blasmediums (1A) in Kunststoffformlinge, umfassend zumindest einen steuerbaren Ventilkörper (1), zumindest eine Betätigungseinrichtung (2), sowie eine Steuerungseinrichtung (22) zum Ansteuern der Betätigungseinrichtung (23), wobei die Betätigungseinrichtung zumindest mittelbar in Wirkverbindung mit dem Ventilkörper (1) steht,
wobei die Betätigungseinrichtung (23) zumindest einen Piezoaktor (21) umfasst, wobei über ein Betätigen der Betätigungseinrichtung (23) und einem damit einhergehenden Ansteuern des Piezoaktors (21) durch die Steuerungseinrichtung (22) in Abhängigkeit des in den Piezoaktor eingeprägten Stroms und/oder der an diesen angelegten Spannung der Ventilkörper von einer Offen-Stellung in eine Zu-Stellung und umgekehrt bewegbar ist, und in der Zu-Stellung ein Hauptströmungsweg (1B), zur Einleitung des Blasmediums in die Kunststoffvorformlinge, verschlossen ist.
